Study On The Safe Driving Assistant System Of Fixed-Line Highway Passenger Transportation

Vehicles of passenger transportation driving on the fixed-line, often encounter intersection, blind bend and bridge, tunnel or changes in the road alignment, all this require driver take the appropriate measures, there will be a series of corresponding driving moves,sometimes it require driver do decision-making rapidly when the dirver is very strained. the long journey in such a tense situation, are likely to cause traffic accidents. This article through analysis the characteristic and the cause which the accident occurs to the fixed line, based on the gathering data of typical driving scene with fixed-line, launches to research on safe driving assistant system of Fixed-line, which in order to reduce pilot's working strength and the traffic accident, safeguards on some fixed routes vehicles of passenger transportation convenient, security, quick, the effective operation.This topic union safe driving pattern under special scene, Author exploits safe driving assistant system of fixed-line with high-level programming language Visual Basic and MapX5.0 of components GIS products. Based on the total design of the system, modules, system design and implementation of key technologies, This paper adropts modern communication and control technique,achieved to deal with GPS vehicle navigation and supervisor control center, using projection match method to solve the position track of vehicle on electronic map when GPS information is lost. The system realizes reception of data used GPS receiver as a data terminal equipment, navigation data will be transmitted to computer through the computer serial. accomplish electronic maps module design with MapX, use this components in VB6.0 need IDispatch which call member function through a standard automation interface, thus achieving the purpose of controlling and operating the electronic route map, and then realized early warning function.
